Definitions

  • the present invention has as its object a matrix for supporting dental fillings during hardening thereof, the matrix being transparent to ultraviolet rays and to the rays of the visible spectrum to permit rapid hardening by polymerization of the filling material and of a material which does not adhere to that of the said filling.
  • Matrices for dental use are already known, transparent to ultraviolet rays and to the rays of the visible spectrum, of material which does not adhere to that of the filling, each characterized by a transparent plate preferably made of plastic material, bent to adhere perfectly to the shape of the tooth in course of filling so that after introduction into the cavity of the tooth, of the filling material and the matrix applied holding it for some time with a forceps and causing the matrix to be passed through by a beam of ultraviolet or luminous rays for a few seconds, starting the polymerization process of the filling material which permits of removing the matrix and of continuing the irradiation until its complete hardening takes place (see in this respect Swiss Patent No. 626'247 filed on the 2nd August 1978) by the same applicant).
  • the matrix according to the present invention differs from that described above by the fact that it can be adapted to a great diversity of shapes of teeth by which with a limited range of matrices the dentist can meet all the demands that is, adapt them to the shape of incisor, canine teeth, molar teeth of adults and children.
  • a concave elastic lamina having a radius of curvature less than that of the various teeth to which it may be applied and thinned at a portion of its circumference so as to be able to penetrate under the gum, the lamina being provided at the rear with a stem to allow it to be grasped with forceps and pressed strongly against the tooth to be treated, thereby increasing its radius of curvature so that it can adapt to the shape of the tooth to which it is applied.
  • the matrix consists of a lamina 1 of elastic transparent material preferably made of thermoplastic synthetic resins permeable to ultraviolet rays and to the visible rays of the spectrum and concave with a radius of curvature "r" less than that of the various teeth to which it may be applied so that when the stem 2 is grasped with forceps and is pressing it against the tooth to be treated increasing its radius of curvature it assumes perfectly the shape of the said tooth whichever it may be.
  • the filling material hardenable by polymerization under the action of ultraviolet rays of the visible light of the spectrum there is applied onto the tooth the matrix according to claim 1 pressing it strongly against the tooth by means of the forceps which holds it by its stem so that it (matrix) assumes perfectly the shape of the tooth, there is then caused to pass ultraviolet or visible radiation through the matrix holding it always by its stem until the beginning of the polymerization of the filling material and when this material is sufficiently hardened the matrix is removed and the irradiation is continued until complete polymerization.
  • synthetic resins for realizing the matrix in question are selected those which do not adhere to the filling material and which are transparent to the aforesaid radiations.
  • the resin constituted by a polymer of methyl penthene is especially suitable for the purpose.
